Il piede (piedi quadrati, abbreviazione: ft; simbolo: ', il simbolo primo) è un'unità di lunghezza nei sistemi di misurazione usuali e statunitensi. Dal 1959, entrambe le unità sono state definite da un accordo internazionale equivalente a 0,3048 metri esatti. In entrambi i sistemi, il piede comprende 12 pollici e tre piedi compongono un cortile.
